NOW Sunflower Lecithin has phosphatidyl choline, the most abundant phospholipid in the cell membrane, where it plays a key role in cellular signaling and synaptic function. NOW Sunflower Lecithin also naturally abounds in phosphatidyl inositol, phosphatidyl ethanolamine, and essential fatty acids. Lecithin in the diet aids in emulsyfying fats, enabling them to be dispersed in water; and as a choline-containing phospholipid, its choline is easily absorbed and utilized by the body.* NOW Sunflower Lecithin is non-GMO and soy free.
